Recirculating Thermostats Accessories

PROCHILL laboratory thermostats are characterized by their compact design combined with high power density. At temperature equilibrium, a cooling capacity of 600 watts is ensured. A comprehensive range of accessories simplifies the integration of the LABCHILL Peltier recirculating thermostat into laboratory or industrial applications.

Glycotherm® heat-transfer liquids

Water-glycol mixtures for use at especially at low temperatures. Our Glycotherm products are available as Glycotherm 5, Glycotherm 20 and Glycotherm 30 with an operating temperature range down to -5 °C, -20 °C and -30 °C, respectively.
Additionally, the composition of the substances prevents algae formation during operation and thus ensures trouble-free use in your application.

Silotherm® Silicone oils

Silotherm silicone oils are especially suitable for use at high temperatures at which water or glycotherm products could outgas. The viscosity of our Silotherm silicone oils is also specifically matched to the operation with LABCHILL and PROCHILL recirculating thermostats.

Connection hoses

Our connection hoses enable quick and safe installation of the cooling-heating thermostats to the respective application.
The self-sealing connectors allow for a plug & play connection without the danger of liquid leakage when connecting the hose.

Insulated connection hoses

Insulated connection hoses are particularly suitable for applications with high temperature differences to the ambient temperature. The insulation prevents additional energy input in cooling mode or energy loss in heating mode of the cooling-heating thermostats. Our insulated hoses are also equipped with self-sealing connectors.

Possible application areas of PROCHILL Peltier recirculating thermostats include, among others:

To ensure operational reliability, process engineering applications and systems depend on dissipating the thermal waste heat of certain components. In addition, temperature stability and control accuracy are crucial in analytical processes to achieve optimal results. PROCHILL not only meets these requirements but also enables straightforward installation in standard racks thanks to its compact design with just four height units as a 19″ rack-mounted unit. Like all our Peltier recirculating thermostats, our LABCHILL devices are also refrigerant-free and offer largely maintenance-free operation.

Laser sources

Temperature control plays a crucial role in ensuring repeatable operation in many applications. One example is laser sources, which only operate with high precision at a constant temperature. Accurate temperature regulation ensures stable operation and minimizes the risk of failures. In addition, precise temperature control protects against overheating and thus prevents potential damage to the system. With the right thermal management, reliable and efficient system operation is ensured, enabling optimal results and high process reliability.

Semiconductor industry

Precise temperature control of, for example, chucks ensures optimal positioning accuracy in the semiconductor industry. The use of communication interfaces enables comprehensive process monitoring, allowing for optimal control. Various parameters can be monitored and adjusted if necessary. This not only contributes to efficient operation but also increases system reliability.

Cooling of UV lamps

PROCHILL offers an ideal solution for cooling UV lamps or during lithographic processes. For example, when curing adhesives using UV lamps, waste heat is generated. Efficient cooling is therefore essential to prevent machine failures. In addition, no maintenance is required, which helps keep operation efficient.

Medical technology

In addition to lithographic processes, imaging and analytical procedures also require cooling and temperature control to ensure that components operate reliably and without failure. PROCHILL provides excellent solutions not only for these challenges in medical technology. Especially in analytics, the highest level of precision in temperature control is essential. PROCHILL ensures precise temperature regulation even in demanding applications, delivering reproducible and accurate results.

FAQ

PROCHILL offers a cooling capacity of 600 watts at temperature equilibrium between the circulating medium and the ambient temperature. This makes PROCHILL the most powerful thermoelectric cooling and heating thermostat in its class. Operation for cooling high-performance laser heads is therefore also possible. Our experts are happy to check at any time whether the cooling capacity is suitable for your specific application.

Upon request, both the PROCHILL itself and the corresponding connecting hoses can be equipped with custom fittings.

We recommend operating PROCHILL cooling and heating recirculating thermostats with the tested accessories designed for them. These include suitable connection hoses as well as temperature control fluids from the Glycotherm and Silotherm brands.

PROCHILL thermostats can be operated with water, water-glycol mixtures, as well as silicone oils.

The PROCHILL features a silent mode and a boost mode. In silent mode, the fan speed is minimized to ensure the quietest possible operation. In boost mode, the Peltier performance is maximized in order to achieve the steepest possible temperature ramps.

The PROCHILL cooling and heating thermostat is currently available with a cooling capacity of 600 watts. Further variants will follow. If you have a specific application that requires a different cooling capacity, please do not hesitate to contact us.

The PROCHILL ensures temperature stability better than 0.05 °C. If your application requires particularly precise temperature control, the cooling and heating thermostat can also be calibrated to avoid deviations. In addition, an external temperature sensor can be used to measure the temperature directly at the application.
